Using a Web search engine is one of today’s most frequent activities. Exploratory search activities which are carried out in order to gain knowledge are conceptualized and denoted as Search as Learning. In this paper, we introduce a novel framework model which incorporates the perspective of both psychology and computer science to describe the search as learning process by reviewing recent literature. The main entities of the model are the learner who is surrounded by a specific learning context, the interface (...) that mediates between the learner and the information environment, the information retrieval backend which manages the processes between the interface and the set of Web resources, that is, the collective Web knowledge represented in resources of different modalities. At first, we provide an overview of the current state of the art with regard to the five main entities of our model, before we outline areas of future research to improve our understanding of search as learning processes.

Summary A new reply to the old question as to meaning and foundations of the Lorentz transformations is given by passing over to non-linear equations. Thus, it is possible to show that the theory of special relativity can be based upon the Galilei transformations, i. e. on the classical assumptions concerning space and time, if terms of the fourth order are neglected. The new theory will probably give rise to a revision of relativistic mechanics.

Fueled by ever-growing amounts of (digital) data and advances in artificial intelligence, decision-making in contemporary societies is increasingly delegated to automated processes. Drawing from social science theories and from the emerging body of research about algorithmic appreciation and algorithmic perceptions, the current study explores the extent to which personal characteristics can be linked to perceptions of automated decision-making by AI, and the boundary conditions of these perceptions, namely the extent to which such perceptions differ across media, (public) health, and judicial (...) contexts. Data from a scenario-based survey experiment with a national sample (N = 958) show that people are by and large concerned about risks and have mixed opinions about fairness and usefulness of automated decision-making at a societal level, with general attitudes influenced by individual characteristics. Interestingly, decisions taken automatically by AI were often evaluated on par or even better than human experts for specific decisions. Theoretical and societal implications about these findings are discussed. (shrink)

Theo C. Meyering, in “Mind Matters: Physicalism and the Autonomy of the Person,” takes yet a third approach to the issue of reduction. He states that “if (true, downward) mental causation implies nonreducibility [as Stoeger and Murphy argue] and physicalism implies the converse, it is hard to see how these two views could be compatible.” Meyering distinguishes three versions of reductionism: radical (industrial strength) physicalism; ideal (regular strength) physicalism, and mild or token physicalism. Radical physicalism asserts that all special (...) sciences are reducible to physics in the sense that their laws can be deduced via bridge laws from those of physics. Ideal physicalism asserts that while it is practically impossible to reduce the special sciences, such reduction would be possible were there an ideally complete physics" (Note: This distinction parallels Stoeger’s recognition that epistemological reducibility is relative to the meaning of “laws of nature). Token physicalism is ontologically reductionist: there are no events that are not “token-identical” with some physical event or other (Note: See above, sec. 3.3). However, there are no identities between higher-level and lower- level types of events; consequently some events described by the special sciences have no physical explanation at all. -/- All of these reductionist positions are to be contrasted with compositional (milder than mild) physicalism, which asserts that some higher-level events are not even token-identical with physical events because the higher-level event (say, a crash in the stock market) is constituted by innumerable physical particulars in all sorts of states and interactions. -/- Meyering then surveys some of the existing arguments for the nonreducibility of the special sciences. One of the most important is the argument from multiple realizability. The claim is that economics, for example, is not reducible to physics because economic concepts (for example, monetary exchange) are “wildly multiply realizable” (for example, using coins, strings of wampum, signing a check). Thus, there can be no bridge laws and no reduction. Such an argument, however, only cuts against radical physicalism, not the weaker (and a priori more plausible) ideal physicalism. -/- A stronger argument for the indispensability of special-science explanations is based on the role of functional explanations. For example, the functional description of aspirin as an analgesic is in some instances a more useful explanation of its causal role (relieving a headache) than is its description as the chemical level. -/- Meyering’s own contribution focuses neither on multiple realizability of supervenient properties nor on multiple “fillers” of functional roles, but on “multiple supervenience.” In particular, a single subvenient state of affairs (for example, a cloud of free electrons permeating the metal of which a ladder is constructed) may realize a variety of supervenient dispositional properties (in this case, electrical conductivity, thermal conductivity, opacity). An explanation (say, of the cause of a deadly accident) requires reference to the dispositional property (electrical conductivity), not merely to the subvenient property. Meyering argues that it is this possibility of multiple supervenience, not multiple realizability, that gives arguments against reduction based on functional properties their real force. Downward causation, then, can be understood in terms of selective activation of one of several dispositional properties of a lower-level state, and thus can be assigned a stable place in our picture of how the world is organized without upsetting our conception of physics as constituting a closed and complete system of physical events.

The brain adapts to changes that take place in the body. Deprivation of input results in size reduction of cortical representations, whereas an increase in input results in an increase of representational space. Amputation forms one of the most dramatic disturbances of the integrity of the body. The brain adapts in many ways to this breakdown of the afferent–efferent equilibrium. However, almost all studies focus on the sensorimotor consequences. It is not known whether adaptation takes place also at other “levels” (...) in the system. The present study addresses the question whether amputees dream about their intact body, as before the amputation, or about the body after the amputation and whether the dream content was a function of time since the amputation and type of amputation. The results show that the majority of the dreamers reported dreams about their intact body although the mean time that elapsed since the amputation was twelve years. There is no clear relation with the type of amputation. The results give modest evidence for the existence of a basic neural representation of the body that is, at least, partly genetically determined and by this relatively insensitive for changes in the sensory input.

Summary On the Theory of the Lorentz transformations. A Reply.

"Philosophical Foundations of India" is a 1945 work by Theos Bernard. Within it, he attempts to outline the fundamental principles of the six classic systems of Hindu philosophy, namely: Nyaya, Vaisesika, Samkhya, Yoga, and Vedanta. Presented in a clear, easy-to-understand form, this volume is highly recommended for those looking for an introduction to Indian philosophy and related subjects. Contents: "Preface," "Introduction," "Nyaya," "Vaisesika," "Semkhya," "Yoga," "Mimamsa," "Vedanta," "Kasmir Saivism," "Bibliography," "Glossary." Theos Casimir Bernard (1908-194) was an author and explorer most (...) famous for his work on yoga and religious studies, especially Tibetan Buddhism. Other notable works by this author include: "Heaven Lies Within Us" (1939), and "Penthouse of the Gods" (1939). Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, high-quality, modern edition complete with a specially-commissioned new biography of the author. (shrink)

Peptidylprolyl‐isomerases (PPIases) comprise of the protein families of FK506 binding proteins (FKBPs), cyclophilins, and parvulins. Their common feature is their ability to expedite the transition of peptidylprolyl bonds between the cis and the trans conformation. Thus, it seemed highly plausible that PPIase enzymatic activity is crucial for protein folding. However, this has been difficult to prove over the decades since their discovery. In parallel, more and more studies have discovered scaffolding functions of PPIases. This essay discusses the hypothesis that PPIase (...) enzymatic activity might be the consequence of binding to peptidylprolyl protein motifs. The main focus of this paper is the large immunophilins FKBP51 and FKBP52, but other PPIases such as cyclophilin A and Pin1 are also described. From the hypothesis, it follows that the PPIase activity of these proteins might be less relevant, if at all, than the organization of protein complexes through versatile protein binding.

In this paper, we argue that ‘good care’ in residential nursing homes is enacted through different care practices that are either inspired by a ‘professional logic of care’ that aims for justice and non-maleficence in the professional treatment of residents, or by a ‘relational logic of care’, which attends to the relational quality and the meaning of interpersonal connectedness in people’s lives. Rather than favoring one care logic over the other, this paper indicates how important aspects of care are constantly (...) negotiated between different care practices. Based on the intricate everyday negotiations observed during an ethnographic field study at an elderly nursing home in Germany, the paper puts forth the argument that care is always a matter of tinkering with different, sometimes competing ‘goods’. This tinkering process, which unfolds through ‘intuitive deliberation’, ‘situated assessment’ and ‘affective juggling’ is then theorized along the conceptualization of a ‘practical ethics of care’: an ethics which makes no a priori judgments of what may be considered as good or bad care, but instead calls for momentary judgments that are pliable across changing situations.

This monograph presents new ideas in nomic truth approximation. It features original and revised papers from a philosopher of science who has studied the concept for more than 35 years. Over the course of time, the author's initial ideas evolved. He discovered a way to generalize his first theory of nomic truth approximation, viz. by dropping an unnecessarily strong assumption. In particular, he first believed to have to assume that theories were maximally specific in the sense that they did not (...) only exclude certain conceptual possibilities, but also that all non-excluded possibilities were in fact claimed to be nomically possible. Now, he argues that the exclusion claim alone, or for that matter the inclusion claim alone, is sufficient to motivate the formal definition of being closer to the nomic truth. The papers collected here detail this generalized view of nomic truthlikeness or verisimilitude. Besides this, the book presents, in adapted form, the relation with several other topics, such as, domain revision, aesthetic progress, abduction, inference to the best explanation, pragmatic aspects, probabilistic methods, belief revision and epistemological positions, notably constructive realism. Overall, the volume presents profound insight into nomic truth approximation. This idea seeks to determine how one theory can be closer to, or more similar to, the truth about what is nomically, e.g. physically, chemically, biologically, possible than another theory. As a result, it represents the ultimate goal of theory oriented empirical science. Theo Kuipers is the author of Studies in Inductive Probability and Rational Expectation, From Instrumentalism to Constructive Realism and Structures in Science. He is the volume-editor of the Handbook on General Philosophy of Science. In 2005 there appeared two volumes of Essays in Debate with Theo Kuipers, entitled Confirmation, Empirical Progress, and Truth Approximation and Cognitive Structures in Scientific Inquiry. (shrink)

Physicalism ? or roughly the view that the stuff that physics talks about is all the stuff there is ? has had a popular press in philosophical circles during the twentieth century. And yet, at the same time, it has become quite fashionable lately to believe that the mind matters in this world after all and that psychology is an autonomous science irreducible to physics. However, if (true, downward) mental causation implies non-reducibility and Physicalism implies the converse, it is hard (...) to see how these two views could be compatible. This paper reviews some classical arguments purportedly showing how the autonomy of the special sciences can be upheld without violating the laws of physics or the principle that physics constitutes a complete and closed system. These arguments are presented in order of increasing strength, indicating how the more popular arguments in fact fall short of establishing anti-reductionism of the intended kind. New arguments are added which claim to demonstrate quite effectively how downward causation is possible compatibly with the reign of physics. The paper begins with a section which distinguishes various kinds of reductionism. (shrink)

David Theo Goldberg engages Achille Mbembe in a wide-ranging conversation on the key lines of analysis of Mbembe’s book, The Critique of Black Reason. The discussion ranges across a broad swath of key themes: the constitutive feature of racisms in the making of modernity and modern capitalism as conceived through the global black experience; the African and French archives in constituting, resisting, and refashioning ‘black reason’ and its multiple registers; the centrality of slavery to this constitution and resistance; thinghood (...) and humanity; liberalism as the basis for racial pessimism. The discussion closes with Mbembe’s plea for a shared being and an exchange about repair and reparation. (shrink)

Kepler hat zwei Generationen vor Newton auf der Grundlage des Aristotelischen Bewegungsgesetzes eine Himmelsmechanik entwickelt, die eine dynamische Begründung der drei von ihm entdeckten Planetengesetze lieferte. Leibnizens Himmelsmechanik folgt zwar durch Berücksichtigung der Beschleunigung der Newtonschen Dynamik, stimmt aber andererseits in wesentlichen Zügen auch mit der Keplerschen Version überein. Die drei Himmelsmechaniken Keplers, Newtons und Leibnizens stehen gemäß der Kuhnschen Terminologie in einem revolutionären Verhältnis zueinander. Gleichwohl können Argumente angeführt werden, die die Bevorzugung der Newtonschen Himmelsmechanik gegenüber ihren Konkurrentinnen im (...) Sinne des kritischen Rationalismus berechtigt erscheinen lassen. (shrink)

By way of mathematical demonstration proof is given that the Lorentz transformations can completely be based upon the theory of absolute time, i. e. upon the Galilei transformations . Thus, it becomes evident that the theory of special relativity does not imply a revolution of classical kinematics, let alone of idealistic theory of knowledge.

Dividido entre a filosofia e a poesia, Hölderlin e seu drama incompleto A morte de Empédocles são hoje peças essenciais para se pensar o trágico na Modernidade. Ponte entre a nostalgia da Antiguidade e uma filosofia que nega o projeto metafísico do Idealismo Alemão – projeto que Hölderlin, ironicamente, ajudou a erigir – esta empreitada hölderliniana é uma singular investigação não somente da relação entre arte e pensamento, mas também coloca em questão a constituição da própria Modernidade.

The biological body: The body as thing in a postphenomenological perspective In phenomenology the lived body (le corps vécu) is considered as the subject of reflection while the biological body (le corps objective) is destined for medical sciences. As an alternative I give a view on the basis of the philosophical anthropology of Helmuth Plessner who thinks a person as a subject to have a lived body (Leib) and a biological body (Körper) from an eccentric or third perspective (excentric positionality). (...) A person experiences herself from that eccentric point of view as a lived body and at the same time as a biological and instrumental body. These two perceptions can only be characterized as a dual aspect (Doppelaspekt), and cannot be separated from each other. Plessner moreover considers the biological body as a thing among other things. I place this bodily thing in a postphenomenological perspective as worked out by Don Ihde and discuss the idea to consider it as a mediating thing between the person who has it and at the same time is it as a lived body in the world she lives in. I work out the effects on the person in case of organ transplantation or implantation of artefacts in the postphenomenological perspective of the embodiment and the hermeneutic relation. I conclude that from that perspective both relations appear to be too simple to elucidate what really takes place in a patient and suggest that in case of incorporation of organs or artefacts the postphenomenological mediating relations should be expanded to a triadic (semiotic) variant of mediating technologies that considers the biological body itself as mediating thing in order to encompass the whole of the human experiences including meaning.

An interesting consequence of the structuralist theory of truth approximation, as developed in my From Instrumentalism to Constructive Realism, henceforth ICR, concerns so-called ‘inference to the best explanation’. It will be argued that this popular rule among scientific realists can better be replaced by, various kinds of, ‘inference to the best theory’.

There are two principles which bear the name Frege''sprinciple: the principle of compositionality, and the contextprinciple. The aim of this contribution is to investigate whether thisis justified: did Frege accept both principles at the same time, did hehold the one principle but not the other, or did he, at some moment,change his opinion? The conclusion is as follows. There is a developmentin Frege''s position. In the period of Grundlagen he followed to a strict form of contextuality. He repeatedcontextuality in later (...) writings, but became less strict. From 1914 on,pushed by the needs of research, he comes close to compositionality. Buthe could never make the final step toward compositionality forprincipled reasons, therefore he always would reject compositionality. (shrink)

This book presents the first accessible analysis of Spinoza's Tractatus Theologico-politicus, situating the work in the context of Spinoza’s general philosophy and its 17th-century historical background. According to Spinoza it is impossible for a being to be infinitely perfect and to have a legislative will. This idea, demonstrated in the Ethics, is presupposed and further elaborated in the Tractatus Theologico-politicus. It implies not only that on the level of truth all revealed religion is false, but also that all authority is (...) of human origin and that all obedience is rooted in a political structure. The consequences for authority as it is used in a religious context are explored: the authority of Scripture, the authority of particular interpretations of Scripture, and the authority of the Church. Verbeek also explores the work of two other philosophers of the period - Hobbes and Descartes - to highlight certain peculiarities of Spinoza's position, and to show the contrasts between their theories.

Theo Verbeek provides the first book-length examination of the initial reception of Descartes’s written works. Drawing on his research of primary materials written in Dutch and Latin and found in libraries all over Europe, even including the Soviet Union, Theo Verbeek opens a period of Descartes’s life and of the development of Cartesian philosophy that has been virtually closed since Descartes’s death. Verbeek’s aim is to provide as complete a picture as possible of the discussions that accompanied the (...) introduction of Descartes’s philosophy into Dutch universities, especially those in Utrecht and Leiden, and to analyze some of the major problems that philosophy raised in the eyes of Aristotelian philosophers and orthodox theologians. The period covered extends from 1637, the year in which Descartes published his _Discours de la Méthode, _until his death in 1650. Verbeek demonstrates how Cartesian philosophy moved successfully into the schools and universities of Holland and how this resulted in a real evolution of Descartes’s thought beyond the somewhat dogmatic position of Descartes himself. Verbeek further argues that this progression was an essential step in the universal propagation of Cartesian philosophy throughout Europe during the second half of the seventeenth century. As he details the disputes between Cartesians and anti-Cartesians in Holland, Verbeek shows how the questions raised were related on the one hand to religious conflicts between the Remonstrants and the Orthodox Calvinists and on the other hand to political conflicts between more liberal factions fighting for the union of church and state to enhance religious control of society in general. Contending that Descartes and Cartesian philosophy were central to the development of the modern Dutch state, Verbeek illuminates the role they played in Dutch political, religious, and intellectual life.

BackgroundThe SARS-CoV-2 pandemic has highlighted once more the great need for comprehensive access to, and uncomplicated use of, pre-existing patient data for medical research. Enabling secondary research-use of patient-data is a prerequisite for the efficient and sustainable promotion of translation and personalisation in medicine, and for the advancement of public-health. However, balancing the legitimate interests of scientists in broad and unrestricted data-access and the demand for individual autonomy, privacy and social justice is a great challenge for patient-based medical research.MethodsWe therefore (...) conducted two questionnaire-based surveys among North-German outpatients (n = 650) to determine their attitude towards data-donation for medical research, implemented as an opt-out-process.ResultsWe observed a high level of acceptance (75.0%), the most powerful predictor of a positive attitude towards data-donation was the conviction that every citizen has a duty to contribute to the improvement of medical research (> 80% of participants approving data-donation). Interestingly, patients distinguished sharply between research inside and outside the EU, despite a general awareness that universities and public research institutions cooperate with commercial companies, willingness to allow use of donated data by the latter was very low (7.1% to 29.1%, depending upon location of company). The most popular measures among interviewees to counteract reservations against commercial data-use were regulation by law (61.4%), stipulating in the process that data are not sold or resold (84.6%). A majority requested control of both the use (46.8%) and the protection (41.5%) of the data by independent bodies.ConclusionsIn conclusion, data-donation for medical research, implemented as a combination of legal entitlement and easy-to-exercise-right to opt-out, was found to be widely supported by German patients and therefore warrants further consideration for a transposition into national law.

What meaning does the theological notion of discernment have in a postsecular cultural condition? Three levels of the meaning of postsecular are distinguished: first, the ‘postsecular’, as a notion that characterises a cultural condition, mainly in Western society, full of diverse religious expressions; second, ‘postsecularity’, as a reflective model for interpreting religious expressions and behaviour; and third, ‘postsecularism’, as a cultural-philosophical or theological programme. After elucidating the concept of the postsecular, we consider some key elements in discernment, investigating the subject, (...) the nature and the object of discernment. We then turn to Richard Kearney’s Anatheism as a fine example of how the notion of discernment receives a new usage in postsecular reflection. We ponder upon his idea of discernment as ‘prereflective carnal response to the advent of the Other’ and reflect upon its meaning for postsecular thinking. The concluding section offers a consideration of the meaning of Kearney’s interpretation of discernment for judgement in postsecular culture. (shrink)
